Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 66 words
In a process for hydrocracking a hydrocarbonaceous feed under hydrocracking conditions, the improvement comprising contacting a hydrocarbonaceous feed with a catalyst composition comprising a zeolite having a mole ratio of an oxide selected from silicon oxide, germanium oxide, and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, and mixtures thereof greater than about 5:1 and having the X-ray diffraction lines of Table 1.
Claim 2
Dependent Claim 66 words
In a process for hydrocracking a hydrocarbonaceous feed under hydrocracking conditions, the improvement comprising contacting a hydrocarbonaceous feed with a catalyst composition comprising a zeolite having a mole ratio of an oxide selected from silicon oxide, germanium oxide, and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, and mixtures thereof greater than about 5:1 and having the X-ray diffraction lines of Table 1.
